The majority of brands went the humorous route, such as San Diego Zoo’s unsatisfied gorilla and the zombie video for Brooks Running Shoes that Zappos shared. The latter was funny and on brand, since it sells the sneakers in question.

Funny was the most common strategy for brands on Presidents Day, too – the most commonly-attempted strategy, at least. A lot of them were really cheesy (liberty and juiciness, Starburst, really?) while others have much wittier people running their Twitter accounts.

While holidays always get brands on Twitter, the same can be said of big cultural moments. Exhibit A: The Super Bowl. Exhibit B: The Grammy Awards, which took place in Los Angeles on Monday.

(Read more...) of the most active brands on the #TheGrammys hashtag were sponsors, such as McDonald’s, Hilton and Gucci. However, many others got in on the action, particularly fashion brands such as Marc Jacobs, Calvin Klein and Burberry, who let it be known that they dressed some of the stars.

Valentine’s Day and Presidents Day weren’t the only holidays this week. They may not have an entire section of the greeting card aisle or get you a day off work, but being nice and drinking wine are both things worth celebrating, too.

Wednesday marked Random Acts of Kindness Day, a day that was pretty popular among sports franchises. Everyone from the Jacksonville Jaguars to the UFC, which has a big event this weekend in Pittsburgh, was doing giveaways.

Pepsi had a similar strategy, deployed in a different way. Rather than tweet its own offers, the soft drink giant tweeted them directly to consumers who participated in the #RandomActsofKindnessDay hashtag.

Many brands tweeted about Random Acts of Kindness Day, but Whole Foods took it one step further.

The tweet drove people to its Instagram page, where there are more than 140 characters to explain the situation. If you tagged your friend and told Whole Foods what makes them so great, they had the chance to win some free groceries. Both random and kind.

Whole Foods had a good week, Twitter-wise. During National Drink Wine Day on Thursday, the brand was very busy with multichannel marketing. Rather than just tweet pictures of its wine offerings, Whole Foods also directed users to its website, which featured articles on wine trends and recipes.
